probably you meant https://bugs.openjdk.java.net/browse/JDK-8168307

I proposed to do same to investigate the problem. Does it mean that you 
approve the current fix?

But severity of this bug is rather low because it is internal problem 
that does not affect user experience. It may be deferred to the next 
major JDK release.

Also note, that the same bug was already closed as "won't fix" before: 
https://bugs.openjdk.java.net/browse/JDK-5100801
